This was entrancing, meditative, and beautiful. I had a lot of fun playing! The contrast of Stage Four with the rest was very evocative.
As a quick note, I also had the bug where I couldn't progress but found a work around. What happened was that after each new stage, I couldn't see the options that followed it. I think it's possible the issue is a result of #CLEAR working? The issue was fixed by saving and loading.
